A couple days after I passed on this alert to the amazing Charles Cushman photo collection, another reader immediately saw possibilities for this carefully filed and annotated archive of our city in the ’30s, ’40s, and ’50s.

He’s created a Google map, digitally mapping over 200 of the enormous collection’s slides to their places of origin.

This looks like it must have been a TON of work, but as Dan wrote, “Richard — this wasn’t so much effort as it looks. Google maps has a geocoder which takes street intersections and turns them into GPS coordinates. I wrote a script to download the Cushman archive pages, look up the street addresses in the geocoder, and add them to the map.”

Right — it’s easy if you know how! And I suspect that slightly more energy went into this project than Dan is letting on.

Though just a bit over 10% of the 1791 images in the San Francisco portion of the archive were readily identifiable, it’s more than enough to pull you back into a visceral, three-dimensional experience of our city in the era of Kodachrome.
